Reccomended Hard Drive erasing tools

One of the office laptops is being taken out of service as a new one has been purchased.

There is/has been sensitive company data on this drive in the past and so I am taking the necessary steps to make sure that the disk is wiped and not recoverable easily

So far I have used Webroots Win Washer and ran NSA level passes on all options such as IE cache, document history etc. I am currently running an NSA level clean up of free space on the hard drive where previously deleted documents may still reside.

After this has been done I was planning to use the tool supplied with Win Washer to wipe the disk.

Another tool I have downloaded is called Killdisk from LSoft Technologies

I am wanting to stick with freeware tools as there seem to be many that do the job.

Just wondering if I am going about this in a good way and if anybody has any further suggestions!

TIA.

if you figure the cost associated with your efforts and the risk of disclosure of sensitive company information sometimes it is just cheaper to physically destroy the HD and buy a new one.

barring that most 3 level government style wipe disk programs should give you a fairly good protection of wiping the info.

as a final practice reformat the HD with entires of all of one character such as the letter Z.
 
Yup you are doing well but like eyec says - the only truly safe way to protect your data would be to physically destroy the disk - really destroy it!!! There will always be someone somewhere with enough cash and resources to recover any data from any media no matter how much you have wiped it.
 
Thats a fair point, but the information isnt *that* senstitive, not government style or anything just some client information and some other detailed financial stuff etc.

I think the laptop will be given to one of the bosses sons or something like that so it would be taking it a bit far taking a hammer to it....although that would be a good way to relieve the stresses of the day hehe

I like the idea of formatting with all one charatcer, i've heard of this before.

How do I go about doing that?

Thanks for the tips so far, at least I know I am on the right track.

If you want to go the software route here is one I found with Google.
Erasing a hard drive

Do a google and you will find a lot of others.

Thanks, I have already downloaded killdisk - my question was wether what I was doing was a reasonable method.

basically, all disk erasers (the ones that really erase) write binary zeros to the hard disk. you can do this using a vb script. but your easiest bet is get something that does this already out there as described above.
 
I use a much simpler method...as you know you need to do this a least 7 times to be fairly sure the info is overwritten..
1. FDISK the drive to 1 complete paratation
2. Format the drive completely.
3. write the complete drive full I took a 1 GB file and copied over and over
4. repeat step 2 different 1 gb file
5. repeat step 3
do that until you have at least 7 times or buy you a program that will do the same thing it takes ages to do on very large HD's
